我已经切到骨组织 head-to-head 核验子任务，并在 PubMed 上做了定向检索：
- `(bone OR cartilage OR osteoarthritis) (navitoclax OR ABT-263) (OSK OR OSKM OR partial reprogramming)` → **无结果**
- `(bone OR cartilage OR osteoarthritis) head-to-head senolytic reprogramming` → **无结果**
- `("partial reprogramming" OR OSK OR OSKM) navitoclax ABT-263 osteoarthritis` → **无结果**
这说明：至少在 PubMed 可检索原始文献层面，骨/软骨/骨关节炎里尚未出现可直接对照的 OSK vs senolytic 头对头设计。接下来我会把这个子任务标记为失败或证据缺失，并决定是否继续向其它组织平移。
→ call task_fail({"id":"n143","reason":"PubMed 定向检索骨/软骨/骨关节炎中 OSK/partial reprogramming 与 navitoclax/ABT-263 的原始 head-to-head 设计均为 0 命中；目前只能确认比较证据缺失，不能确认存在直接对照。"})

本轮证据结果：
- 骨组织相关定向 PubMed 检索没有找到 OSK vs senolytic 的原始直接对照；
- 也没有找到骨/软骨/骨关节炎里把两条路线放进同一研究、同组织、同终点框架的 head-to-head 文献；
- 因此当前最稳妥结论仍是：**比较证据缺失**，不能从并列正例推出路线优劣。
我把骨组织核验这条子任务判为失败，而不是 done，因为它完成的是“排除存在性”而不是“确认存在”。
<NEXT_FOCUS>继续在其他高概率组织中横向扫描 OSK vs senolytic 是否存在同组织同终点原始 head-to-head 设计，优先寻找能补齐最小可比实验规格的证据。</NEXT_FOCUS>本轮完成了骨组织方向的横向核验，结论是：
- PubMed 定向检索 `(bone/cartilage/osteoarthritis) + (OSK/OSKM/partial reprogramming) + (navitoclax/ABT-263/senolytic)` **没有命中可确认的原始 head-to-head 研究**
- 也没有找到把两条路线放在**同组织、同终点、同研究**框架里的直接对照
- 因而当前只能把结论降级为：**比较证据缺失**，不能据此推路线优劣
任务树更新：
- 新增子任务 `n143: 横向核验骨组织中 OSK vs senolytic 是否存在直接 head-to-head 原始证据`
- 已判定为 **failed**，原因是检索零命中，未能确认存在直接对照
<NEXT_FOCUS>继续在其他高概率组织中横向扫描 OSK vs senolytic 是否存在同组织同终点原始 head-to-head 设计，优先补齐最小可比实验规格。</NEXT_FOCUS>
